Abstract: 1,149,462. Measuring digital displacements. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 16 Aug., 1967 [19 Aug., 1966], No. 37620/67. Heading G4H. Apparatus for measuring digital displacements includes a pick-up device which delivers, after filtering and amplifying, a first signal RB at a reference frequency and a second signal MB, the frequency difference between these signals representing the displacement, multiplication stages 11, 12, 13, and 21, 22, 23 (Figs. 1a, 1b) which form signals 8RB, #8RB, 8MB, #8MB and a phase delaying network 17 which generates from the first signal RB a signal RBE (90 degrees out of phase with respect to the signal 8RB) together with its inverse #RBE. These signals are applied to two exclusive OR gates 30, 31, 32 and 40, 41, 42 (Fig. 1c), the outputs from which are pulse trains S 0 V, S 90 V, the duration of the pulses representing the phase difference between the signals 8RB and 8MB, and RBE and 8MB respectively. These signals are fed via low-pass filters 33, 43 which generate signals S 0 VF and S 90 VF, the amplitude of which represents the phase difference to pulse shaping network 43, 44 to generate square wave signals S 0 , #S 0  and S 90 , #S 90  which have a frequency equal to the frequency difference to be measured. These signals are fed to a known discriminator device which determines the sign of the frequency difference to control the direction of counting in a counter.

Title: Process for the preparation of sultones
IPC: C07D327/02
Filed: 1960-11-03
Abstract: Sultones are produced by heating alkali metal or ammonium salts of sulphonic acids of general formula Hal-R-SO3H, in which Hal is a halogen atom linked to an aliphatic carbon atom and R is a hydrocarbon group containing at least 3 carbon atoms and in which at least 3 carbon atoms are present between the halogen atom and the sulphonic acid group, at temperatures above 150 DEG C. and under reduced pressure.  Suitable acids are, for example, 3-chloropropanesulphonic acid-1, 3-bromopropanesulphonic acid-1, 3-iodopropanesulphonic acid - 1, 4 - chlorobutanesulphonic acid - 1, 3 - bromobutanesulphonic acid-1, 4 - bromobutanesulphonic acid - 2, 1 - chlorohexanesulphonic acid - 4, 4 - chloro - 2 - methyl - pentanesulphonic acid - 2,3 - chloro - octane - sulphonic acid-1, o - chloromethylbenzene - sulphonic acid and 2-chloromethyl-naphthalenesulphonic acid-3.  Preferably salts of halogensulphonic acids having 3 or 4 carbon atoms between the halogen atom and the sulphonic acid group are used as starting materials. The reaction is preferably carried out at a pressure less than 50 mm. Hg and at a temperature between 180 DEG C. and 300 DEG C. There may be added to the reaction mixture inert substances which are good heat conductors, for example, metal turnings, or the heating may be carried out in the presence of an inert substance which is liquid at the reaction temperature.  The halogen-substituted sulphonic acid salts used as starting materials may be prepared, for example, by the reaction of alkylene dihalides with the corresponding sulphite. Alternatively an example describes the preparation of the sodium salt of 3-chloropropane sulphonic acid-1 by reacting the sodium salt of 1-hydroxypropane sulphonic acid-3 with hydrogen chloride.

Abstract: 847,284. Dispensing liquids. AVERYHARDOLL Ltd. Dec. 15, 1958 [Dec. 13, 1957], No. 38852/57. Class 116 [Also in Groups XIX and XXVIII] A piston 24 actuated by a hand lever 14 draws liquid from a pipe 32 and discharges it through a valve 45 to a chamber 23 from which the piston draws the liquid into the upper end of the cylinder and subsequently discharges it to an outlet 37. The piston 24 is coupled through a lost motion connection to a piston 31 in a cylinder 22 so that liquid is drawn from a pipe 33 and discharged to an outlet 41, the degree of lost motion being adjustable to vary the ratio of liquids discharged through the outlets 37, 41, the combined volume discharged being constant. The outlets 37, 41 are connected by a hose to a discharge nozzle. Applied to the dispensing of a petrol/oil mixture the pipes 32, 33, are connected to a petrol tank and oil tank respectively. The volume discharged from the lower portion of the cylinder by the piston 24 is greater than that from the upper so that the chamber 23 is supplied with excess liquid. A float 42 opens the discharge valve 45 when a given level is reached. The handle 14 is connected to the piston through a device ensuring full stroke operation. The handle also actuates a pointer (see Group XIX) indicating the volume discharged and also a total stroke counter; when the discharge nozzle is suspended from a hook the pointer is returned to zero and a bolt engages the handle to prevent operation. Specification 818,966 is referred to.
